Nouveau Can Beat NVIDIA With Cairo In Select Cases

Chris Wilson has shared his testing experience of Cairo with NVIDIA ION hardware on the open-source Nouveau driver and the closed-source NVIDIA blob. In certain situations, the Cairo performance does better with Nouveau than the official NVIDIA Linux driver...

"A few orders of magnitude" means "at least a hundred times", do you really mean that?
